      r'''Calculates droplet removal by a demister as a fraction from 0 to 1,
      using the correlation in [1]_. Uses only their own experimental data.
      
      .. math::
          \eta = 0.85835(d_w)^{-0.28264}(1-\epsilon)^{0.099625}(V)^{0.106878}
          (d_p)^{0.383197}
          
      Parameters
      ----------
      vs : float
          Superficial velocity of fluid, Q/A [m/s]
      voidage : float
          Voidage of bed of the demister material, normally ~0.98 []
      d_wire : float
          Diameter of mesh wire,[m]
      d_drop : float
          Drop diameter, [m]
  
      Returns
      -------
      eta : float
          Fraction droplets removed by mass [-]
  
      Notes
      -----
      No dependency on the liquid properties is included here. Because of the
      exponential nature of the correlation, for smaller diameters separation
      quickly lowers. This correlation can predict a separation larger than 1
      for higher velocities, lower voidages, lower wire diameters, and large 
      droplet sizes. This function truncates these larger values to 1.
      
      The correlation in [1]_ was presented as follows, with wire diameter in
      units of mm, density in kg/m^3, V in m/s, separation in %, and particle
      diameter in mm.
      
      .. math::
          \eta = 17.5047(d_w)^{-0.28264}(\rho_{mesh})^{0.099625}(V)^{0.106878}
          (d_p)^{0.383197}
      
      Here, the correlation is converted to base SI units and to use voidage;
      not all demisters are stainless steel as in [1]_. A density of 7999 kg/m^3 
      was used in the conversion.
      
      In [1]_, V ranged from 0.98-7.5 m/s, rho from 80.317-208.16 kg/m^3, depth 
      from 100 to 200 mm, wire diameter of 0.2 mm to 0.32 mm, and particle 
      diameter from 1 to 5 mm.
